Astronomers using China's FAST radio telescope have discovered a compact hydrogen cloud devoid of visible stars. Containing nearly 500,000 solar masses of neutral hydrogen, it represents one of the strongest candidates yet for an isolated dark galaxy.
An astronomer from the University of Missouri is leading 130 researchers across 62 institutions, including NASA, Caltech, Princeton, and Harvard. The ambitious mission aims to capture an unprecedented view of the early universe.
Astronomers have solved the mystery behind the musical treble clef-shaped radio formation located beyond the Milky Way's Zone of Avoidance. New research confirms that this peculiar cosmic structure is a rare radio phoenix.
The immense mass of the distant El Gordo supercluster challenges cosmological growth models. Researchers suggest this rapid formation could stem from a two-state self-interacting dark matter mechanism.
A peculiar cosmic feature resembling a glowing neon treble clef has been revealed as an energetic radio structure powered by a distant supermassive black hole.
Astronomers have detected a massive black hole tearing apart a star more than 1,000 parsecs from its galaxy's center. The tidal disruption event, TDE 2023mfm, was tracked across multiple observatories.
The Hubble Space Telescope has captured a striking edge-on view of the intermediate spiral galaxy NGC 1827, located approximately 37 million light-years away in the constellation Columba.
Astronomers utilized NASA's Chandra X-ray Observatory to determine the physical causes behind the 'Treble Clef' radio wave structure. The study unveils the dynamics of massive colliding galaxy clusters.
Combining cold dark matter simulations with observations of stellar streams and globular clusters, researchers inferred a declining power-law initial mass function for globular clusters.
The James Webb Space Telescope has detected an unexpected signal twice, 88 days apart, emanating from a patch of space previously thought to be empty. Scientists are evaluating four possible origins.
Globular clusters have far fewer binary stars than the solar neighborhood. New research identifies black hole burning as the culprit.
Astronomers have discovered two actively feeding supermassive black holes separated by only 175 parsecs in a galaxy observed when the universe was roughly 2 billion years old.
After identifying a new globular cluster, HSC 61, belonging to the Sagittarius dwarf galaxy, researchers have mapped the stellar stream, determined its metallicity, and analyzed the Sagittarius merger event.
NASA, Hubble uzay teleskobunun yakaladığı ilginç bir kareyi paylaştı. Kameraya gülümseyen bir galaksi kümesi... ABD Havacılık ve Uzay Ajansı'nın (NASA) Hubble uzay teleskobu, evrenin gizemlerini gözlemlemeyi sürdürüyor. NASA 1990 yılından bu yana yörüngede çalışan Hubbe'ın kaydettiği çarpıcı bir…
The kinematics of small Milky Way satellites should differ depending on whether dark matter is warm or cold; current data constrain the mass of warm dark matter particles to >5.8 keV at 95% confidence.
Take advantage of these moonless evenings! Make friends with some far Cassiopeia clusters in the high-arching Milky Way. Soon the Moon will return.
The stellar gathering known as Garro 04 belongs to a growing number of enigmatic groupings that combine traits of young open clusters ancient globulars.
Mengting Ju et al 2026 ApJL 1002 L18 Using data taken with a novel slit-stepping observing mode, researchers have found an anticorrelation between radial metallicity gradients and radial mixing time for galaxies at z ~ 1.
Image: This NASA/ESA/CSA James Webb Space Telescope Picture of the Month features galaxies in great detail that have been warped and multiplied like they’ve stepped into a house of mirrors. The brilliant golden galaxies splashed across this image belong to a galaxy cluster called MACS J0454.1-0300…
Image: Though the spiral galaxy in this new image by the NASA/ESA Hubble Space Telescope seems serene, it hides a chaotic secret. This galaxy is NGC 4698, and it lies about 55 million light-years away in the constellation Virgo. It’s one of over one thousand galaxies in the Virgo Cluster, the…
An international team of astronomers has discovered the most distant progenitor to a galaxy supercluster ever. The discovery supports existing theories of how galaxy clusters evolve, and reveals how they are connected to the larger cosmic web. The study relies largely on data from the ODIN survey…
